Is mod_ldap really needed?

[rainerjung]

The README.md states:

You need to activate the following module (ldap_module) as well. Normally it is in your server config file, so just uncomment it:
LoadModule ldap_module modules/mod_ldap.so

I am wondering, whether this is true and if so why. I did not find any reference to LDAP in the source code or example config, that would explain, why mod_authn_ntlm needs mod_ldap.

Could you please double check and remove those lines from README.md if not needed.
Thanks a lot!
